The numerical value of 1 + 1 co t^263^ - se c^227^ + 1 ^263^ - cose c^227^ is?

Answer: Option D

$$\begin{array}{rl}& \text{1 + }\frac{1}{\text{co}{\text{t}}^2{63}^{\circ }}-\text{se}{\text{c}}^{2}27^{\circ }\text{ + }\frac{1}{{\sin }^2{63}^{\circ }}-\text{cose}{\text{c}}^{2}27^{\circ }\\ & \Rightarrow 1+\text{ta}{\text{n}}^{2}63^{\circ }-\text{se}{\text{c}}^{2}27^{\circ }+\text{cose}{\text{c}}^{2}63^{\circ }-\text{cose}{\text{c}}^{2}27^{\circ }\\ & \Rightarrow 1+\text{co}{\text{t}}^{2}27^{\circ }-{\sec }^{2}27^{\circ }+\text{se}{\text{c}}^{2}27^{\circ }-\text{cose}{\text{c}}^{2}27^{\circ }\\ & \Rightarrow 1+\text{co}{\text{t}}^{2}27^{\circ }-\text{cose}{\text{c}}^{2}27^{\circ }\\ & \Rightarrow 1-1\\ & \Rightarrow 0\end{array}$$
